Lenovo boasts that the Vibe Z measures just 7.9mm thick, and is available with either a silver or titanium chassis, which the firm claims is laser etched to feel like soft fabric when held in the hand.

Other specifications include 2GB of RAM, 16GB of internal storage, a 13MP rear-facing camera and a 5MP front-facing camera. Full specifications are likely to be revealed at CES next week.

Lenovo SVP Liu Jun said, "We created the new Vibe Z with its elegant design, high performance and custom software so that people can truly have the best smartphone experience now at the speed of LTE.

"Along with the Vibe Z, our new S and A Series smartphones offer consumers choices of screen size and features so they can pick the Lenovo smartphone that’s right for them."

Lenovo's new S and A series smartphone lineups consist of the S930, S650 and A859 models, featuring 6in, 4.7in and 5in displays, respectively.

Lenovo has said that the Vibe Z smartphone will start shipping in February priced at $549. There is no word of a UK release yet. µ
